Correctly arrange them in the order in which they are carried out to handle the interruption of a running user process by assigning a number from 1 through 9 to indicate the precedence order for the following steps.For example, 1 would indicate the first step in the process, 2 would indicate the second in theprocess and so on.

With regard to the performance data cited for programs v, w, x, y, and z in table 11.1, find the geometric means of the runtimes of the programs for System B and System C, using System A as the reference system. Verify that the ratios of the means are consistent with the results obtained using the other two systems as reference systems.
